The Bottlenecks to Survival project is broad and highly collaborative in nature. There are several key project partners including DFO’s Salmonid Enhancement (SEP) and Stock Assessment Division (StAD), the Provincial Ministry of Forests, Lands, and Natural Resource Operations (FLNRO), and the University of Victoria (UVic). These groups contribute vitally in the areas of the scientific study development and on the ground operations. We have also partnered with a number of community groups, non-profit stewardship organizations, and First Nations—whose traditional lands and rivers we are working in—to carry out field programs. Other academic institutions (SFU, UBC) are partners in mutual data collection and field sampling and are providing additional on the ground support. Lastly, the majority of our marine sampling is being carried out by a group of volunteers throughout the Salish Sea region, to whom we are very grateful for their continued efforts and dedication.
